about

nx_nxa_fk.nx -- SHARED integer quaternion + FK primitives for the NXA import pipeline. Extracted from nx_nxa_anim (DRY rule-15: nx_nxa_skin needs the same static-FK to compute TRUE bind positions instead of placeholder propagation; nobody re-derives quat math). q12 fixed-point (unit = 4096); angles arrive as millidegrees; all integer. license_tier: ORIGINAL
